Nicely done, hippies, nicely done. Now if Oregon, Washington state, Vermont & Connecticut, maybe even Colorado & Hawaii follow suit. People always love to make fun of California, including myself, but shit like this is why they will always matter.

California lawmakers are expected to propose legislation to fold existing federal air, water and endangered species standards into state law, sources said, enshrining pre-Trump levels of protection in California regardless of any reversal at the federal level.

The legislation, to be introduced by Senate President Pro Tem Kevin de León and other Democratic senators, would require state air and water pollution regulators to maintain environmental standards at least as stringent as federal law required before Trump took office. And it would add state-level protections for species currently listed as endangered or threatened on the federal Endangered Species Act.

In an effort to impede the Trump administration from transferring federal lands to private developers for oil drilling or other purposes, Democratic lawmakers are also expected to propose a bill to give the State Lands Commission right of first refusal on such transactions.

The legislation marks the latest in an ongoing feud between the president and heavily Democratic California, where Gov. Jerry Brown and Democratic lawmakers are bracing for conflict with Washington on issues ranging from health care to immigration and climate change.

Trump criticized California environmental policies during the campaign and threatened after taking office to withhold funding from California if it moves forward with additional protections for undocumented immigrants.

“California,” he told Fox News' Bill O’Reilly, “in many ways is out of control.”

While California has relied for years on federal waivers from the Clean Air Act to set its own, stricter, clean air standards, Trump’s Environmental Protection Agency administrator, Scott Pruitt, has left open the possibility that the administration could revoke the state’s authority.

Pruitt, one of Trump’s most controversial Cabinet members, has drawn intense criticism from California lawmakers. Following his confirmation last week, de León said in a prepared statement that “California will not follow Trump’s destructive path.”

Washington Gov. Jay Inslee and Oregon Gov. Kate Brown at a joint news conference on Saturday in Seattle said they support more renewable energy, caps on emissions and policies to limit pollution.

“The reason we stopped TrumpCare is because we spoke up and we spoke out,” Inslee said. “We have to do the same thing on the environment. To have a president who will in the next few days or weeks announce that he plans to roll back our efforts to fight climate change is unacceptable.”

The head of the Environmental Protection Agency, Scott Pruitt, on Sunday said that Trump in the coming days will sign a new executive order that unravels the Obama administration’s Clean Power Plan, an environmental regulation that restricts greenhouse gas emissions at coal-fired power plants.
